X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=22e74ef9b59080f4cf880185ec09c483952eb74f;p=binutils-gdb.git

* sparc-nat.c (sparc_fetch_inferior_registers): Explicitly supply
zero as the value for %g0 in the register cache.
* sparc-tdep.c (sparc32_supply_gregset): Likewise.
* sparc64-tdep.c (sparc64_supply_gregset): Likewise.
